Five people were killed and 46 injured in a Ukrainian attack on the southwestern Russian city of Belgorod late on Friday, the local governor said.
Vyacheslav Gladkov said that 37 of the injured, including seven children, were taken to hospital.
Video from a car dashboard, posted on social media and purporting to demonstrate the attack, showed another car being blown up while moving on the road. Seconds later, an explosion is seen on the other side of the road. Reuters could not immediately verify the authenticity of the video.
Russia's Investigation Committee said on its Telegram channel that it had initiated a criminal case into the Belgorod attack.
Authorities also reported that a woman was injured on Saturday during the Ukrainian shelling of the border town of Shebekino in the Belgorod region.
Ukraine has staged frequent attacks on Belgorod and other Russian border regions in recent months. The city has been the focal point of the attacks.
Ukraine and Russia say they do not deliberately target civilians in the war that began when Russia sent thousands of troops to its smaller neighbour in February 2022. Moscow has called the invasion a "special military operation".
